Winterize your Hot Tub Spa

Winterize your Hot Tub Spa – Thermo-Spas

Hot Tub Winterizing/Closing

If you do not plan to use your spa during freezing weather, you will have to winterize it. Failure to winterize your spa will cause irreversible damage (in freezing temperatures) to the pump and plumbing lines.

Winterization of your hot tub is easy. Follow the steps in this checklist each time you drain the water from your spa in freezing temperatures to prevent serious damage from occurring to your hot tub:

Hot Tub Winterizing/Closing Steps

Step 1:

Close all therapy control valves and open all jets.

Step 2:

Turn the spa circuit breaker off.

Step 3:

Drain your spa. We recommend using a submersible pump. If you don’t have a submersible pump, you can attach a garden hose to the hose spigot, located on the primary water pump within the spa interior. Be sure to run the drain line to an area that can handle the drainage. (see Figure 1)

Step 4:

Remove the cabinet panel in front of the spa’s equipment compartment.

Step 5:

Open the hose spigot located near the primary pump to drain any remaining water and leave open afterwards.

Step 6:

Locate the heater and open the heater unions at both ends by turning counter-clockwise. (see Figure 2)

Step 7:

Clear water from the water pump(s) suction and return lines using a canister-type wet vacuum. You MUST use a canister type wet vacuum in order to ensure that the lines are cleared of all remaining water.

Customer ResponsibilitiesAny spa/hot tub is subject to freezing in cold weather. You must follow these procedures during a power failure or if the hot tub spa is not operating properly in order to prevent your hot tub spa from freezing.

Preventative Maintenance During the cold weather season, you should inspect your outdoor hot tub spa every day to insure it is running properly. If you detect a problem and the temperature is dropping, contact the service department immediately during regular working hours. It is the customer’s responsibility to follow the procedures listed above in order to prevent a freeze up.
